Answer:
A
Step-by-step explanation:
The new set of data would be
69, 83, 89, 94, 100 (from least to greatest)
Mean= 87 (You add all of the numbers in the set together, and divide by how many numbers there are)
Median= 89 (the middle number)
Mode= none (There is no number that repeats its self)
Range= 31 (Subtract the greatest number by the smallest number)

Answer:
Part A: 6r + 5
Part B: r = 9
The rectangle measures 20 inches by 59 inches
Step-by-step explanation:
Part A:
(18r^(2)-27r-35)/3r-7
=6r + 5
Part B:
I just divided 1180 by the numbers on the list until I got an answer that was another number on the list. Then i took the greater number, 59, and set 6r + 5 equal to that like so:
6r + 5 = 59
6r = 54
r = 9
and i set 3r - 7 equal to the smaller number, 20:
3r - 7 = 20
3r = 27
r = 9
Hope this helps.
Answer:
x = 19
Step-by-step explanation:
(10x - 23) and (7x + 34) are vertically opposite angles and congruent, so
10x - 23 = 7x + 34 (subtract 7x from both sides )
3x - 23 = 34 ( add 23 to both sides )
3x = 57 ( divide both sides by 3 )
x = 19
